Variable RIB Design Refiner Plate - For Pulp Paper Mills
#PARASON Variable Rib Design refiner plates are manufactured using Special Casting & CNC technology to provide the maximum uniformity in the refining zone. PARASON #VariableRibDesign #refinerplates are manufactured with special cast technology to provide uniform hardness throughout. The plates wear uniformly.
• Suitable for mixed furnish Refining. • Normally long fiber & short fiber need to refine separately with different bar patterns as per required SEL & CEL. • The VRD design is made to deal with mixed furnish. • The peripheral velocity for long fiber zone is little lowered than HW zone which is a need for respective furnish. • The retention time for long fiber is higher than short fiber. • The rib height for long fiber zone is higher & smaller for short fiber zone to give desired refining effect. • This design ensures the minimum shortening or damage to the fiber which give better strength in the paper with higher breaking length. • There is a base taper in the disc for better throughput & optimization of hydraulic capacity of the disc. - SAS design offers close control over cutting angle of refiner disc.
Special Features
